Hi there,
First, I would recommend confirming what actually expired, because OpenVPN setups often hit either the server cert or the CRL:
-
Check server cert expiry:
openssl x509 -in /etc/openvpn/server.crt -noout -dates -
Check CRL expiry (if you use
crl-verifyin the config):openssl crl -in /etc/openvpn/crl.pem -noout -nextupdate
If it is the server certificate, you generally need to issue a new server cert from the same CA. Depending on your Easy-RSA version, that is either a renew command (if supported) or re-issuing a fresh server.crt and server.key, then restarting OpenVPN.
If the CA itself is expired, you are usually looking at reissuing server and client certs.
